Considering the alarming importance of CSAT in UPSC CSE Prelims exam and with enormous requests we received recently, InsightsIAS has started Daily CSAT Test to ensure students practice CSAT Questions on a daily basis. Regular Practice would help one overcome the fear of CSAT too.We are naming this initiative as Insta– DART – Daily Aptitude and Reasoning Test. We hope you will be able to use DART to hit bull’s eye in CSAT paper and comfortably score 100+ even in the most difficult question paper that UPSC can give you in CSP-2021. Your peace of mind after every step of this exam is very important for us.
Looking forward to your enthusiastic participation (both in sending us questions and solving them on daily basis on this portal).

Question 1 of 5
1. Question
Platform-based work is often presented as a new form of economic freedom. By linking workers to customers through apps, it appears to lower barriers to entry, widen earning opportunities, and allow individuals to choose when and how much they work. Yet this flexibility is not experienced uniformly. The worker may be free to log in and out, but rates, visibility, incentives, and even continued access to work are often shaped by algorithmic systems that remain opaque to those who depend on them. A driver or delivery worker may seem independent in legal form while carrying risks that were once absorbed by employers: fuel costs, idle time, fluctuating demand, and the consequences of poor ratings. In such a setting, digital intermediation does not simply remove hierarchy; it may reorganize it in less visible ways. What looks like autonomy on the surface may coexist with new forms of dependence underneath.
Which of the following conclusions is/are valid?
- Platform-based work may combine formal flexibility with hidden forms of control.
- Since workers can choose when to log in, platform work eliminates economic insecurity for them.
Select the answer using the code given below.
Correct
Answer: (a)
Explanation:
Conclusion 1 is valid. The passage clearly says that platform work appears flexible, but that rates, visibility, incentives, and even continued access to work are shaped by opaque algorithmic systems. This supports the conclusion that formal flexibility may coexist with hidden control.Conclusion 2 is invalid. The passage explicitly points to continuing insecurity in platform work through fuel costs, idle time, fluctuating demand, and the effects of poor ratings. The mere ability to log in and out does not remove these risks.
Therefore, (a) is the correct answer.

Question 2 of 5
2. Question
Which of the following reflect the intent of the writer in the above passage?
- To show that the apparent autonomy of platform work may conceal new structures of dependence
- To argue that digital labour platforms should replace all older forms of employment
- To question whether legal independence in platform work corresponds to real economic independence
Select the answer using the code given below.
Correct
Answer: (c)
Explanation:
Statement 1 is correct. The passage repeatedly contrasts the surface appearance of freedom with underlying dependence shaped by opaque systems and transferred risks.Statement 2 is incorrect. The passage does not argue that platform work should replace older employment systems. It is analytical and critical, not prescriptive in that direction.
Statement 3 is correct. The passage explicitly notes that a worker may seem independent in legal form while carrying risks once borne by employers. This directly reflects the writer’s concern about the gap between legal and real independence.
Therefore, (c) is the correct answer.

Question 3 of 5
3. Question
Which of the following statements reflect the logical and rational inferences that can be drawn from the passage?
- Control in platform work may operate through systems that workers do not fully understand or influence.
- Some risks traditionally associated with employment may be shifted from firms to workers in platform-based arrangements.
- The absence of a conventional employer necessarily ensures that hierarchy disappears from work relations.
- Economic dependence can persist even where workers appear free in contractual or legal terms.
Select the answer using the code given below.
Correct
Answer: (b)
Explanation:
Statement 1 is valid. The passage says that algorithmic systems shaping rates, visibility, and incentives remain opaque to the workers who depend on them. This directly supports the inference.
Statement 2 is valid. The passage explicitly mentions fuel costs, idle time, fluctuating demand, and poor ratings as risks carried by workers that were once absorbed by employers.
Statement 3 is invalid. The passage argues the opposite. It says digital intermediation does not simply remove hierarchy; it may reorganize it in less visible ways.
Statement 4 is valid. The final lines of the passage make this clear: what looks like autonomy on the surface may coexist with dependence underneath.
Therefore, (b) is the correct answer.Incorrect

Question 4 of 5
4. Question
If a boat’s speed in still water is a two-digit number P, and the speed of the stream is one-third of P, then:
Statement I: The boat covers 48 km downstream in less than 4 hours.
Statement II: The boat covers the same distance upstream in 6 hours.Question: What is the speed of the boat in still water?
Correct
Answer: (b)
Explanation:
Upstream speed of the boat = P – P/3 = 2P/3From Statement II:
48 km are covered upstream in 6 hours.So, upstream speed = 48/6 = 8 km/h
Therefore,
2P/3 = 8
P = 12So, Statement II alone is sufficient.
From Statement I:
48 km are covered downstream in less than 4 hours.
This means downstream speed is more than 12 km/h.Now downstream speed = P + P/3 = 4P/3
So,
4P/3 > 12
P > 9This does not give a unique value of P.
Hence, Statement I alone is not sufficient.
Therefore, option (b) is correct.
Incorrect
Answer: (b)
Explanation:
Upstream speed of the boat = P – P/3 = 2P/3From Statement II:
48 km are covered upstream in 6 hours.So, upstream speed = 48/6 = 8 km/h
Therefore,
2P/3 = 8
P = 12So, Statement II alone is sufficient.
From Statement I:
48 km are covered downstream in less than 4 hours.
This means downstream speed is more than 12 km/h.Now downstream speed = P + P/3 = 4P/3
So,
4P/3 > 12
P > 9This does not give a unique value of P.
Hence, Statement I alone is not sufficient.
Therefore, option (b) is correct.

Question 5 of 5
5. Question
There are 18 seats arranged in a circular hall, numbered 1 to 18 clockwise. A marker is initially placed on Seat-1. The marker is moved clockwise.
In the first move, it advances 1 seat.
In the second move, it advances 3 seats.
In the third move, it advances 5 seats, and so on, increasing by 2 seats each time.After how many moves (including the starting position) will the marker again be on Seat-1?
Correct
Answer: (b)
Explanation:
After n moves, total advance = 1 + 3 + 5 + … up to n terms = n².
For the marker to return to Seat-1, n² must be divisible by 18.
Now,
18 = 2 × 3²
So n² must contain 2 and 3².
Therefore, n must contain 2 and 3.
Least such n = 6
Since the question asks including the starting position, total count = 6 + 1 = 7
Hence, the correct answer is (b).Incorrect
